The idea of a win for a 25 second pin is actually more combat realistic than you might think. A 25 second pin free from your opponents legs gives sufficient time to finish an opponent with ground and pound or the samurai days to draw a blade, and kill you opponent.

Missed this comment..

The picture of how it was painted to me by someone that knows more about judo than i, and probabally more than most people to be fair -

Leg attacks have been ommitted beacuse eastern europeans had that bent over style and attacked legs, eg double legs, firemans carry. Legs attacks were seen by some as being 'ugly judo'. So they where taken away and the japanese style was adopted i.e a more up right posture and spectator friendly as the throwing techniques are often 'cleaner' from this position.

You talk about judo pinning being realistic? -
The sport has become badly diluted. The realistic nature of the sport becomes less and less with every rule chance and its all about the spectator and participation levels and not the pureness of the sport as it once was imho.

Also, there is no ground n pound in judo, its adopted in mma which is of course 'no gi' which could be argued that a wrestling technique was employed to get him there, not judo. After all it is the oldest sport known to man and judo was spawned from it..

Just thought I'd jump in and say, I like it that throws like Morote Gari are now banned and would earn Hansukomake. I dont know why, I just didnt like the throw. And I know a few people who won round after round in comps just shooting for the legs. When they took the leg attacks away, those people really had to learn to break balance and attack properly. Someone I know, a very strong 1st Kyu has won a few tournaments in the past with morote garis. He has a good understanding of techniques but put him into shiai or even randori and he has such a problem grip fighting and breaking balance that he seldom manages to pull off throws like seois and koshi waza.
Hence now he is struggling to get points for his dan grade.

Leg attacks are still very much alive in tachi waza, as bomberh said as counters or combinations. They are super useful if you use the opportunities wisely. I still dont to be honest and need to make my awareness of leg attacking opportunities better, but its there all the same.

The difference leg wise though is that in Ne-waza competition within the BJA, leg locks are not allowed as submissions. But leg work IS allowed in movement and osaekomi etc.

Just thought Id add, I think a wrestler is far more used to grappling without a gi and that would work in his favour. Put him in a gi and of course he would be totally lost against the control and maniuplation of a judoka with a gi to grip.
But, yes without, to a judoka who never fights without a gi, they would need to think from scratch about where they would hold for throws. Im sure they would work it out soon enough though. If you find a good grip to break balance and throw with uchi mata, you'd do it. I doubt the wrestler would defend against it would they? I dont know much about wrestling admittedly.

One thing to think of though. Judoka are very very good at avoiding landing on their backs. And when they throw someone, they should be ending up in an advantageous position.
Whenever I have watched a good judoka in MMA, even when they get thrown, they seem to land on top.
